When I was in high school, we had a little kitchen disaster. My mom always turned the stove on high to get it warmed up more quickly. One day, when I was in the basement doing something, she called to me saying that she had just put something on the stove and to come up in 5 minutes and turn it down. She needed to run to the store. Of course, I totally forgot. At some point, I heard a loud bang. I went upstairs to find the kitchen filled with what looked like fog. Through the fog, I could see the burner on the stove glowing red. When I took a breath, I almost choked. I opened the side door, took a deep breath, and went over the turned the stove off. I then went back in several times opening doors and windows to let the toxic fog out.
When it finally cleared, I saw that the bottom of the large heavy pot that she used for pot roasts had melted. The "fog" was actually a toxic metallic haze. The kitchen and the adjoining living room had to have all new paint and wallpaper and I think some of the furniture had to be replaced.
